TEA TTLE.

T0 alliwhom it may concern Be it known that I, HARoLp E. CASLER, a

citizen of the -United States of: America,

residing 'at Charlotte,

Teakettles, ofw-hich the following is a; speciaccompanying drawing. 7

This invention relates to a tea kettle, and has for its principal object theproduction of a simple and eflicient means for utilizing the heat for heating the contents of the kettle in the shortest possible time.

Anotherobject of this invention is production of 'a receptacle having a. flue formed therein, whereby the heat may be conducted through the flue which is positioned within the receptacle thereby increasing theheating surface. within the receptacle and in this. manner heating thecontents of the receptacle in the shortest possible time.

A still further object of this invention is the production of a heating element for various receptacles which has a dome fixedly mounted within the. receptacle adjacent the bottomthereof, whereb the dome. will collect heat and discharge the heat into the ec nn c he m nd exten in within the receptacle to communicate with e x rio he f, where y a arge, he t.- ingarea is formed wherebythe contents oi the ep a l 1l-be atedm0ne q i kly With these and other objects in view this invention consists of certainnovel constructions, combinations and arrangements of parts as will be hereinafter fully described and claimed.

In the accompanying drawings:

Figure l is a side elevation of a tea kettle illustrating the exterior appearance thereof with the heating device attached.

Fig. 2 is a central horizontal section through the tea kettle showing the flue in a top plan.

Fig. 3 is a bottom plan view of the device.

Fig. 4 is a section taken on the line 1- 1 of Fig. 2.

Application filed September 24 1917. Serial No. 192,953. 1

Fig. 6 is an enlarged fragmentary sectional view through a portion of the kettle and the dome, illustrating the manner in which this dome is formed. I

Fig: 7 is a fragmentary sectional view 'jthrough a pair of lengths of pipe used in forming the flue.

Fig. .8 is. a longitudinal section through a receptacle, such for instance as a boiler, showing a slightly heating device.

Fig. 9 is a detailed perspective'view' of one modified form of the dome and pipe which the same applied to the tea kettle or other receptacle.

Referring to the accompanying drawings a by numerals, it will be seen that the tea kettle comprises a bottom 1 having a wall 2 secured as shown at 3 in the usual manner,

while the wall 2 is provided with a top 4 iodifiedtorm oi the illustrating in dotted lines the manner in having an outwardly extending annular flange 8 formed upon its lower portion and this collar 7 projects through the bottom 1 of thetea kettle so, as to cause the flange 8 to engagethe under surface of the bottom 1 so as t bejSecuredf by any suitable means such as solder for causing the dome to be fixedly mounted; upon 'the-Jteakettle. The'top 9 of the heating dome fits upon the outwardly extending annular flange 10 formed upon the upper edge of the collar 7 and this top 9 is provided with an overhanging flange 11 from which the annular lip 12 extends and the flange l1 and lip 12 will engage the flange 10 thereby permanently securing the top 9 upon the collar 7. While flanges will hold the heating dome in a set position, it is obvious that suitable material may be applied tothe joints so as to prevent the heating, dome from leaking.

The flue comprises a plurality of pipes 13 having their ends extendin sli htly into each other as shown at 14 in ig. It is of course obvious a single length of pipe may be applied for constituting the flue. Short pipes 15 are carried by the pipes 13 and one of these short pipes 15 projects through the collar 7 into the interior of the heating Wall 2 so as to communicate with the exterior I dome as shown in Figs. 2 and' l, while the remaining short pipe projects through the of the tea kettle. It will be noted however, that these plpes constltute the flue for receiving heated air gathered by the heating dome and then conduct the heated air through the flue and discharge the heated" air adjacent the outer side of the tea kettle.

This flue is spaced from the bottom of the tea kettle and extends for a considerable dis tance around the heatingdome so as to present the maximum heatingsurface around I which the contents of the tea kettle will rest, thus increasing the heatingsurface. I '1 By referring to Fig. 8 it will be seenthat a boiler is shown which comprises the usual bottom 16 having a side wall 17 carried thereon. The heating "dome comprises the collar 7 having a top 9 secured thereto as shown atlO'. 3 7 J The flue comprises straight pipes 18'eX-f tending from opposite sides of the heating- 22 is of a coil construction having an S, shaped portion 23 projectin through the outer surface of the tea kett the same'is carried. I I

The heating dome and .flu'e may be used upon receptacles of various designs without departing from the I spirit of the invention, and therefore, it is not intended to limit the construction of this devicelto the, specific form herein suggested, for it is intended to include-all such forms of the invention as A 1 communicating with the into rig. 91min be seenthat' I a bell-like heating dome 21 is provided upon which thereis formed apipe'22.
